I have a P85D and reside in Las Vegas, we do not get up to 50 C, prob highest around 46. I actually do not notice that big of a range difference, average around 320 where normally it is around 300. This is of course with the AC blasting. I notice a much bigger loss in range when it is very cold outside.
